I'm not a rock climber, but a bowhunter trying to better my equip. Thought I'd join up here to get some tried and true answers regarding descenders.

I'm in a full body harness, but need a controlled descent solution for about 30ft. My personal needs: has to work if unconcious, lightweight, tangleprooof, idiot proof, ease of use in darkness. I'm 6ft, 200#, 54years. If I fall, I just want to get to ground safely within a few minutes. This was suggested and looks good, but all thoughts appreciated.

I have never used this type of equipment. Again, regards to all, and thanks ahead of time.

There is no such device.

You can find some that are lightweight and might be easy to use by some in the dark, but that is as far as matching your needs goes. Nothing is idiot proof and I can't see one implementing a device for rapping while unconscious. For it to be tangle proof on it's own is possible, but usually requires human attention.
